 · Process for reducing the grain size of phosphate rock Only coarse grained phosphate rock with a grain size over 2 mm from the last screen classifiion step is fed to a plainroller grinding mill. The rollers of the grinding mill run at different peripheral speeds, so that the grains are ground by radial and tangential forces.

Particle size measurement is an important role in the utilization of phosphate rocks for nanofertilizer. In this study, the phosphate rocks from Wonosari and Ciamis were milled by planetary ball mill (PBM) into submicron size ( μm). Measurements of the submicron size were conducted using a dynamic light stering (DLS) method, ...
